| Abstract: | This paper presents a probabilistic greedy pursuit(PGP)algorithm for compressed wide-band spectrum sensing under cognitive radio(CR)scenario.PGP relies on streaming compressed sensing(CS)framework,which differs from traditional CS processing way that only focuses on fixed-length signal's compressive sampling and reconstruction.It utilizes analog-to-information converter(AIC)to perform sub-Nyquist rate signal acquisition at the radio front-end(RF)of CR,the measurement process of which is carefully designed f... |
